CONCRETE-MIXER.

Specification of Letters Patent.

Patented 001;. 26, 1am.

Application filed November 11, 1913. Serial No. 800,242.

To all whom it may concern:

Be it known that 1, JOHN F. KLANN, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Concrete-Mixer, of which the following is a specification.

This invention relates to a concrete mlxer, and one object of the invention is to provide an efficient mixer which may be hand operated and economically constructed.

A further object is to enable the mixer to be employed as a vehicle for carrying the material to the place where it is to be used, the mixer acting to mix the materials while they are being thus transported.

Referring to the drawings: Figure 1 is a plan view of one form. Fig. 2 1s a s1de elevation of the form shown in Fig. 1. Flg. 3 is an end elevation. Fig. 4 is a section on line m-*x*, Fig. 1. Fig. l is a detail sectional view showing by dotted lines the position of the receptacle when tilted, and in solid lines the normal position of the receptacle.

Briefly, my invention consists of a receptacle in which the materials are adapted to be placed, such as the cement aggregate and water, and then the receptacle rolled along to mix the materials and at the same time transport them.

In the form shown in Fig. 1, 1 designates a receptacle with beveled ends 2, one end being open at 3 and the other open end being provided with a spout 4. The receptacle is formed internally with a series of wings 5 which act to pick up and mix the material within the receptacle as the same is rolled along. The material is placed in the receptacle through the opening 3 and is discharged from the receptacle through the spout 4, the discharge being accomplished by tipping the receptacle on one of its flanges 6 which acts as a fulcrum. This operation is clearly shown in Fig. 4 by dotted lines.

In order to easily roll the receptacle along, I provide a chain 7 operating over idle sprockets 8 and driven by driving sprocket 9 having a crank 10. The chain 7 engages the materials to the desired point.

depressions 11 which are formed in the shell of the receptacle. The receptacle may roll on a platform or tracks 12. Thus when at one end of the tracks 12, the receptacle may be charged with the materials and then by rolling the receptacle along the track it will mix the materials and at the same time transport The rims 6 fit loosely in the tracks 12 so that one of the rims may turn in its track to enable the receptacle to be tilted to dump its con tents through its open end after the concrete has been thoroughly mixed and the receptacle has been rolled along the tracks to the point where the concrete is desired. It will be understood that the chain 7 is loose enough to allow it to be raised so as to clear the flange 6. The grooved tracks prevent the fulcrumed flange slipping during the dumping operation. 7

What I claim is:

1. In combination, a mixing receptacle provided with an open end, a pair of annular flanges located intermediate the ends of the receptacle and surrounding said receptacle, a pair of grooved tracks along which said flanges are adapted to roll, means for rotating said receptacle to cause the receptacle to travel along said tracks and to mix its contents, one of said flanges being adapt ed to turn in its track to enable the receptacle to be tilted to dump its contents through its open end.

2. In combination, a mixing receptacle provided with an open end, a pair of annular flanges located intermediate the ends of the receptacle and surrounding the receptacle, a pair of tracks along which said flanges are adapted to roll, a sprocket on said receptacle, a chain engaging said sprocket, means for driving said chain to enable the chain and sprocket to rotate said receptacle to cause the receptacle to travel along said tracks, and to mix its contents, one of said flanges adapted to turn in its track to enable the receptacle to be tilted to dump its contents through its open end.

3. In combination, a track, sprockets at the ends of said track, an endless sprocket chain extending along the track and row around my hand at Los Angeles, California this 2-l said sprockets, a mixing receptacle tiltably day of October, 1913. mounted to roll on the track and having means engaging the sprocket chain, and 5 means to turn one ofthe sprockets to thereby roll said receptacle along the track.

In testimony whereof, I- have hereunto; set

JOHN F. KLANN.
